Server-side scripting in python

[Nagarajan]

Hi group,
I need to develop a web application. I am in a fix as to choose among
the various server-side scripting options. I want to explore python
(am a newbie) to gain expertise and upon search, I learnt about
PSP(Python Server Pages) that uses Jython as its scripting language.
Is it a better option over PHP or Perl? Could anyone point out the
pros and cons of using PSP over others?

Help much appreciated.
